view contents of packages
My printer driver came as a mac
.pkg program that wouldn't install because it was too old. I figured that inside it had the content, probably in PDFs or HTML files, and I wanted to get at it.
Fortunately, I learned that Mac finder has a "show package contents" functionality if you right-click on a
.pkg file, which will let you pull out individual files.
Inside a second
.pkg inside the primary
.pkg, I found the directory full of HTML files that I was looking for and I have no need of the program. Success!
